Tuna, I think this does what you want.

If an element exists in %HoL_compare_pub, but not inside %HoL_pub, then push it into the array-ref $no_matches{$key}:

my %no_matches;

foreach my $key (keys %HoL_compare_pub) {
  push @{$no_matches{$key}}, $HoL_compare_pub{$key}
    unless exists $HoL_pub{$key};
}
